Red Yellow Green Nutritional Guide
The Red Yellow Green (RYG) system is a simple to understand yet effective way of constructing a nutritional plan to help individuals with PWS. The basic stoplight analogy makes a clear distinction between what is healthy and what is not by putting food into easily understandable categories: foods that can be eaten in abundance, foods to eat in moderation, and foods that should be avoided.
